I have a new 2010 Genesis Sedan with 1000 miles and the multimedia controller failed after about 3 weeks. I was zooming on the map when suddenly the screen went from color to grey and back to color. After that the controller failed. Turning the knob left or right gets' no response. I can still press on it and rock it and it works. Anyone else experience this problem? The dealer ordered a new control unit but it won't arrive until mid to late August, which is BS! I really like this car, but I am not getting a good feeling about this on a brand new car.
